The 802.3af PoE Gigabit Injectors are interoperability with other PoE equipment.
The 1-port model (LPJ001A-F) provides 19.6 W of safe PoE power. The multi-port versions provide 15.4 W per port of safe PoE power to each PoE device attached.
And they support connections to Cisco® legacy equipment, too. On the RJ-45 connections 10/100/1000Mbps midspan data connections are possible.

The 1-port model offers overload and voltage control and provides fully compliant detection and disconnect. The protection includes over voltage/over current overload and short circuit protection on the power output (per 802.3af specifications). Diagnostic LEDs indicate adverse power conditions. A red "FAULT" LED signals to you an overload or short circuit. It aso detects unstable current measurements, low voltage, incorrect resistive signature, and more.

The 8-, 16- and 24-port models feature in addition an over-temperature protection, that provides automatic shutdown without causing any damage. They have also a USB port for diagnostics and manual port control via a Windows® GUI. Or use the diagnostics LEDs for 802.3at device detection and alert.

Avoid the cost and hassle of installing AC power at a remote camera or door scanner. Use these injectors to power IP phones, security cameras, wireless network access points, Bluetooth® access points, IP print servers, and other 802.3af-compatible equipment.

The installation is simple plug-and-play. The light and compact one-port model can be easily wall mounted. The multi-port models are just 1U high. They are easy to install in a rack or cabinet with the included mounting kit.
